About PNG
Portable Network Graphics
A lossless raster format published in 1996 as a patent-free replacement for GIF. It compresses with DEFLATE and supports full alpha transparency. Use it for screenshots, logos and graphics with sharp edges or text, where JPG compression would leave visible artifacts.
About SGI
Silicon Graphics Image
The raster format of Silicon Graphics workstations, also seen with the .rgb and .bw extensions, stored raw or with run-length encoding. Convert from SGI to open images from old IRIX software and 3D pipelines.
